Geof:
When I had both axels, and locked the differential between, both sets of tires spun, this was bob tailed on a gravel incline. From what I know about traction, especially in snow, you want minimal surface area and a deep lugged tire that will not pack with snow. Don't know jack about big trucks, but I have lived in Mn for 50 plus years.
Have a good one
Chuck
